Two developers are working together on a project, and they have built out a set of shared servers that both developers can access over the internet. Which of the following cloud models is this an example of?
A. Hybrid
B. Public
C. Private
D. Community
Show Answer
Correct Answer: B
Explanation: This best fits a public cloud: the shared servers are accessible over the internet. A community cloud is typically shared by multiple organizations with specific common requirements, which the scenario does not describe.
Question 182
Which of the following licensing models is MOST appropriate for a data center that has a variable daily equipment count?
A. Per site
B. Per server
C. Per user
D. Per core
Show Answer
Correct Answer: A
Explanation: A per-site license covers equipment within the data center location, so a changing daily equipment count does not require adjusting the license for each server or core.
Question 183
Which of the following is a type of replication in which all files are replicated, all of the time?
A. Constant
B. Application consistent
C. Synthetic full
D. Full
Show Answer
Correct Answer: A
Explanation: Constant replication continuously keeps files replicated as they change. Full replication copies all files during each replication run, but does not necessarily run continuously.
Question 184
A server has experienced several component failures. To minimize downtime, the server administrator wants to replace the components while the server is
running. Which of the following can MOST likely be swapped out while the server is still running? (Choose two.)
A. The power supply
B. The CPU
C. The hard drive
D. The GPU
E. The cache
F. The RAM
Show Answer
Correct Answer: A, C
Explanation: Server power supplies and drives are commonly designed to be hot-swappable, allowing replacement while the server is running (with appropriate redundancy and support). CPUs, GPUs, cache, and RAM generally require the server to be powered down.
Question 185
A systems administrator is performing maintenance on 12 Windows servers that are in different racks at a large datacenter. Which of the following would allow the
administrator to perform maintenance on all 12 servers without having to physically be at each server? (Choose two.)
A. Remote desktop
B. IP KVM
C. A console connection
D. A virtual administration console
E. Remote drive access
F. A crash cart
Show Answer
Correct Answer: A, B
Explanation: Remote Desktop lets the administrator maintain the Windows servers over the network, while an IP KVM provides remote keyboard, video, and mouse access. Neither requires visiting each rack. A virtual administration console generally applies to virtual machines, which the question does not specify.
Question 186
Which of the following ensures a secondary network path is available if the primary connection fails?
A. Link aggregation
B. Most recently used
C. Heartbeat
D. Fault tolerance
Show Answer
Correct Answer: D
Explanation: Fault tolerance provides redundancy so a secondary network path can take over if the primary connection fails. Link aggregation primarily combines links to increase bandwidth, though it can also provide resilience in some configurations.
Question 187
A datacenter technician is attempting to troubleshoot a server that keeps crashing. The server runs normally for approximately five minutes, but then it crashes.
After restoring the server to operation, the same cycle repeats. The technician confirms none of the configurations have changed, and the load on the server is
steady from power-on until the crash. Which of the following will MOST likely resolve the issue?
A. Reseating any expansion cards in the server
B. Replacing the failing hard drive
C. Reinstalling the heat sink with new thermal paste
D. Restoring the server from the latest full backup
Show Answer
Correct Answer: C
Explanation: A failure that repeatedly occurs after a few minutes under steady load most strongly suggests the server is overheating as it warms up. Reinstalling the heat sink with fresh thermal paste can improve heat transfer and resolve the problem.
Question 188
Which of the following access control methodologies can be described BEST as allowing a user the least access based on the jobs the user needs to perform?
A. Scope-based
B. Role-based
C. Location-based
D. Rule-based
Show Answer
Correct Answer: B
Explanation: Role-based access control assigns permissions according to a user’s job role, limiting access to what is needed to perform that role’s duties.
Question 189
After the installation of an additional network card into a server, the server will not boot into the OS. A technician tests the network card in a different server with a different OS and verifies the card functions correctly.
Which of the following should the technician do NEXT to troubleshoot this issue?
A. Remove the original network card and attempt to boot using only the new network card.
B. Check that the BIOS is configured to recognize the second network card.
C. Ensure the server has enough RAM to run a second network card.
D. Verify the network card is on the HCL for the OS.
Show Answer
Correct Answer: D
Explanation: The card works in another server, so the next step is to check whether it is supported by this server’s operating system. The different OS in the test system does not confirm compatibility with the affected server’s OS.
Question 190
A backup application is copying only changed files each time it runs. During a restore, however, only a single file is used.
Which of the following backup methods does this describe?
A. Open file
B. Synthetic full
C. Full incremental
D. Full differential
Show Answer
Correct Answer: B
Explanation: A synthetic full backup copies changed data incrementally, then combines it with the existing full backup to create a current full backup. A restore can therefore use that single synthetic full backup. Incremental backups require a chain of backups, while differential backups require the last full backup plus the latest differential backup.
